Tracking Adjustment
Zero turn tractors should drive in a straight line with the wheels going straight forward and WITHOUT
having to “steer” the unit straight. If the tracking is off and the person “forces” the unit to drive straight
by steering it straight, there can be whining from one of the hydros if there is enough traction to load up
the hydro. On grass, this would probably result in turf tear. If the user points the unit forward and drives
it, tracking will be off if the rear wheels determine where the unit goes. The unit will drift to one side or
the other as the steering wheel “follows” where the back wheels are driving the unit.
1. Safely raise unit so rear wheels are off the
ground. Insert jack stands.
2. Place a piece of tape on each rear wheel and on
the consoles, aligning the pieces of tape.
3. Have another person sit in the seat with a stop
watch.
4. Start the engine. Press the parking brake switch
to turn off the parking brake.
